JTA — Former Arizona congresswoman Gabrielle Giffords has moved home to Tucson.

Giffords and her husband, astronaut Mark Kelly, reportedly bought a home recently in Tucson and moved in on Sunday. She had spent the last year-and-a-half in Houston undergoing rehabilitation after being shot during a constituent event in Tucson in January 2011.

The Arizona Democrat resigned from Congress in January to concentrate on her rehabilitation. She will continue her therapy in Tucson, according to the Arizona Daily Star.

Kelly had been living in Houston, but has since retired from the NASA space agency.

Giffords, who is Jewish and a member of a local synagogue, was shot in the head at a Jan. 8, 2011 meet-the-constituents event outside a supermarket in Tucson. The gunman, Jared Loughner, killed six people. Giffords was among 14 people wounded.

Loughner last week changed his plea to guilty in the attack. The change reportedly was in exchange for a plea bargain that would send Loughner to prison for life.

He has been diagnosed with schizophrenia; Loughner was declared mentally competent to understand the charges against him.
